Title: Improvements in or relating to photopolymerisable elements
IPC: C08F2/46
Filed: 1958-08-20
Abstract: 841,454. Photosensitive elements and processes for preparing printing relief images. DU PONT DE NEMOURS & CO., E. 1. Aug. 20, 1958 [Sept. 16, 1957], No. 26809/58. Drawings to Specification. Class 98(2) The element comprises a support having a layer of an addition-polymerizable ethylenically unsaturated liquid or solid component, a photoinitiator for polymerization thereof, and a thermo-inhibitor for such polymerization, the stratum of the layer more remote from the support containing at least 1À5 times the amount of inhibitor in the stratum nearer the support. The layer may have a plurality of strata of decreasing concentration of initiator and increasing inhibitor starting from the support, and various arrangements for this are described. Exposure as to a broad light source through a negative and removal of unpolymerized portions of the layer produces printing characters with upper portions having nearly straight sides which do not appreciably broaden as the plate wears down with use and lower portions of increasing breadth and great strength. 150 line halftone negatives may be used. The layers may contain organic or inorganic filler materials, thus in Example I a composition comprising cellulose acetate hydrogen succinate, triethylene glycol diacrylate, anthraquinone, mucochloric acid and hydroquinone methyl ether on an aluminium support overcoated with the same composition but which has three times the proportions of the last ingredient, the inhibitor, is exposed to a 2000 watt mercury arc through a negative and washed with dilute caustic soda solution to produce a plate for printing by means of a flat-bed press. Example II specifies cellulose acetate as filler, the same unsaturated component triethylene glycol diacrylate, benzoin as initiator and 2, 6-di-tert-butyl-p-cresol as inhibitor in two layers with more initiator and less inhibitor nearer the support and such after exposure is processed by washing with acetone. Example III quotes four pairs of solutions using acetone as solvent for producing the elements. Numerous further filler materials, unsaturated components, initiators, inhibitors and supports are quoted and instructions concerning exposure and antihalation features are provided. Specifications 741,441, 741,570, 771,145 and 783,555 are referred to.

Title: Improved System for Producing Alternating Current
IPC: H02P9/42
Filed: 1967-06-12
Abstract: 1,166,196. Standby supply systems. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. 12 June, 1967 [23 June, 1966], No. 27015/67. Heading H2H. A system for producing alternating current of substantially constant frequency and voltage from a variable speed source, such as a ship's propeller shaft, comprises a synchronous machine 10 driven from the source 13 feeding load bus-bar 16 through a frequency changer, such as an uncontrolled rectifier 14 and inverter 15, and a synchronous condenser 17 normally supplying reactive current but which may supply active power on stoppage of the source 13 by being coupled to a prime mover 19 such as a diesel engine. The inverter may be controlled by known means for producing substantially constant frequency and voltage. The inverter firing angle may also be dependent on power output, rate of change of frequency or power output. The condenser 17 may be provided with automatic voltage control and the excitation of the machine 10 may be dependent on bus-bar frequency or rate of change of current. Combined power and frequency regulation may be provided. A capacitor 25 may be paralleled to the condenser through a choke 26, or through a tapping on a common choke (26a) (see Fig. 3, not shown). The machine 17 may be started in an asynchronous mode by a temporary direct connection from generator 10 and the choke 23 is shortcircuitable by a switch 24 when the condenser is being driven as a generator. For stable operation, the short-circuit current of the rectifier should be smaller than that of the condenser 17, also the voltage of generator 10 should fall more rapidly than that of condenser 17, e.g. due to a higher short-circuit reactance winding. A plurality of inverters may be employed having phase displaced outputs, and the resonant frequency of the capacitor choke combination is preferably tuned to the sixth harmonic where the inverter produces fifth and sixth harmonics. A plurality of systems may have their outputs paralleled to bus-bars 16, see Fig. 6 (not shown), and cross-coupled transformer windings may ensure satisfactory load division (see Fig. 7, not shown). The inverter 15 may include thyratrons or thyristors. Where the excitation of machine 10 exceeds a determined value, e.g. under short-circuit conditions, a means may be provided for automatically disconnecting unessential loads and reducing the retardation of the inverter firing angle. Speed control of the machine(s) 17 may control the bus-bar frequency.
